Increase in the rate of the Québec sales tax (QST) as of January 1, 2012

Hello everyone,

Please note that the rate of the Québec sales tax (QST) will increase in 2012.

At the moment, the QST rate is 8.5%. On January 1, 2012, it will go up to 9.5%. The Québec sales tax is calculated based on the amount of sales, including the goods and services tax (GST).

Measures that must be taken

  • All customers who are tax registrants will be responsible for changing the QST rate on their sales invoices.
  • This increase also applies to customers using the Quick Method of Accounting.
    Therefore, those using this method must be aware of the impact of this change.


We hope that this information will be useful to you and, most of all, that you will apply it.

Please do not hesitate to contact us if you have any questions.
